- POST REPORT, Kathmandu

May 16, 2015-

The National Seismological Centre (NSC) recorded at least eight tremors between 2:15am and 5:19pm on Saturday which, according to seismologists, were the aftershocks of the April 25 Great Quake.

The strongest temblor on Saturday measured 5.5 on local magnitude which occurred at 5:19pm with Dolakha district as its epicentre, and its waves were felt as far as India and Bangladesh.

The previous tremors of the day measured between 4 and 4.2 on local magnitude with epicentres in Gorkha, Dolakha (twice), Nuwakot, Dhading, Gorkha/Dhading, Sindhupalchok, and Lalitpur/Makwanpur.

While the NSC said it registered more than 200 moderate to strong aftershocks since the April 25 main shock of 7.6 local magnitude that originated in Gorkha district, the US Geological Survey (USGS) had measured the Gorkha quake at a moment magnitude of 7.9.

Seismologists say the frequency of aftershocks will decrease with time. The strongest aftershock triggered by the Gorkha quake so far occurred on May 12, measuring 6.8 on local magnitude; USGS had measured the same temblor at a moment magnitude of 7.3.
